Answer 2

Fungsi Naik dan Turun

№. 24
g(x) = 2x³ - 9x² + 12x

Naik → g'(x) > 0

g'(x) > 0
6x² - 18x + 12 > 0
6(x - 1)(x - 2) > 0
x < 1 atau x > 2

Interval fungsi naik :
x < 1 atau x > 2

№. 25
f(x) = x³ - ax² + bx

turun → f'(x) < 0
2 < x < 6

f'(x) < 0
3x² - ax + b < 0
(3x - 6)(x - 6) < 0

a = 3(x1 + x2) = 3(2 + 6) = 24
b = 3(x1 × x2) = 3(2 × 6) = 36
